Methods for producing a dielectric, dielectric having self-generating pores, monomer for porous dielectrics, process for preparing poly-o-hydroxyamides, process for preparing ploybenzoxazoles, and processes for producing an electronic component

Poly-o-hydroxyamides include binaphthyl substituents as repeating units. The poly-o-hydroxyamides can be cyclized to give the polybenzoxazole by heating. Pore formation occurs, so that a dielectric having a very low dielectric constant k of less than 2.5 is obtained.
